LIGHTENING STRIKES


Recommended Posts

HI, ALL

Hear is a link that might help out http://www.srh.weather.gov/srh/jetstream/lightning/positive.htm
this high voltage site is whear it came from and was posted in the high voltage stuff by Audioguru http://205.243.100.155/frames/longarc.htm#Disconnect ther is a 
pic of a lightening strike down the page :o

Hi Steven,

Thanks for the whether link interesting reading and fantastic pictures, this confirms that there are both positive and negative lightning. Scary thing “300,000 amperes and one billion volts!” :o  :o  for how long period would you need this to fully charge a car battery? ;D

I heard the thunder from positive lighning that zapped a kid on his bike near my home. He is very lucky to still be alive but is badly burned. It was sunny and the storm was far away. :'(

A car battery and everything near it would be vapourized with 300,000A and a billion volts! ;D

HI, prateeksikka

this is the 1st link on the page and might help out http://plaza.ufl.edu/rakov/ICLP2000/positive1.16.pdf  ;D

To out run a lightening bolt you need to run at 60000 miles a second  :o

I have been trying to get a pic of a lightening bolt but they are toooooooo fast

Hi Steven,

If you try to take pictures of a thunderstorm at night it’s easier, just let the shutter stay open and you can get several lightning bolts on the same pic. That is if your camera allows you to keep the shutter open continuously or for a longer fixed time interval sometimes 4 or 8 sec or even longer.  8) 
 

Audioguru, No of curse you can’t let all of that energy run straight into the accumulator! :D  You have to catch it first in a capacitor and then feed it through a resistor into the battery nice and easy!  ;D What size of cap (uF) do you figure it would take to store the energy from a lightning bolt? 8)

Ok, I'm not sure if anyone said this yet, but here is how part of lightning works:

Whichever one is negative (the clouds or the ground, not quite sure) induces the opposite charge on the other thing. If that makes sense. Basically if the clouds are heavily negatively charged, when they pass over the earth they induce a strong positive charge on the surface. That makes the negatively charged ions in the clouds want to travel towards the earth. Then, once enough of those ions have accumulated, they go ahead and do that. Now as i said, it might be the other way around, I'm not quite sure, but this should give you a pretty good idea of how it works.

The only thing i never really looked at is HOW the charges get so great in the clouds/ground which then induce the charge on the other thing.

for the cap size i'm thinking somthing around 1,000,000,000,000,000,000,000,000uf and a very hi voltage cap too what would that be like the size of my house  ;D or bigger :)
EDIT the cap size would probably be 1,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,
000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000
